I didn't really want to hire a DJ for my wedding. I made playlists and developed a request system. But I also needed a way for someone to pause and speak announcements over a microphone. I found a few winamp plugins that were DSP based, but I didn't like the way the audio delayed. I decided to write a quick app to control the microphone and sound mixer. I think it works great for simple events when you need to simply talk on the sound system. Configure it to pause winamp when you talk. Or configure it to turn down winamp's volume while you talk. The program runs always on top so that you can navigate your music and control the mic at the same time. Source for the app is also available for download. Enjoy.
